The film features a main theme composed by Golden Globe and Grammy-nominated composer Benjamin Wallfisch, who's grandmother, Anita Lasker-Wallfisch, is a survivor of Auschwitz and Bergen-Belsen. Anita was forced to play the cello in the Auschwitz Women's Orchestra and Ben's theme was composed partially for solo cello in honor of his grandmother.
The film was shot entirely with a one-person crew. The director, Ashton Gleckman, filmed and conducted all the interviews, traveled and filmed in Poland, gained film materials from the United States Holocaust Museum, and more completely alone at the age of eighteen.
In preparation for making the film, the director went through dozens of hours of raw uncut interviews from Claude Lanzmann's iconic documentary, "Shoah," filmed in the 1970s and 1980s. Some of this footage ended up in the final film - courtesy of the United States Holocaust Memorial Museum, who acquired the footage in 1996.
This is the first feature film from director Ashton Gleckman.
